Judith MacFayden, from Reading, said: ‘I noticed that I had a “thank you” email from Deliveroo for a burger joint in Chiswick. I thought that was really odd so I went on to my account and had a look and there had been four orders that afternoon to a couple of addresses in London.’

And Margaret Warner, from Manchester, said she was charged £113.70 from her account for a phantom chicken, waffles and chips order. Steve Tappin, similarly, was charged £98 for a TGI Friday delivery – 86 miles away from his home.

All three customers had their money refunded.

Deliveroo said that it wasn’t their system that was compromised, but that hackers had used passwords obtained by other sites’ breaches to access people’s accounts.

‘Customer security is crucial to us and instances of fraud on our system are rare,’ Deliveroo said in a statement. ‘But where customers have encountered a problem, we take it very seriously.’

The company added that the cases reported ‘involve stolen food, not credit card numbers’: ‘These issues occur when criminals use a password stolen from another service unrelated to our company in a major data breach.’

What should I do if someone has hacked into my account?

First thing you should do is immediately change your passwords for all of your accounts.

Then check if they’ve taken any money or placed any orders on your account – if so, call your bank and have them stop the transaction. If it was through a third-party payment service like PayPal, call them too.

See if the hackers have left any of their personal details around. For example, if they’ve ordered stuff from your account they may have left a delivery address and phone number for themselves. Make a note of these.

Then finally, call Action Fraud on 0300 1232040 to report the fraud to the police. Alternatively, you can report the crime using their online form.
